Chieftains can be a real problem when attempting this medal as stick grenades will just bounce off their armor, though it won't bounce off their weapons. You may get a lucky stick on a Gravity Hammer or Fuel Rod Gun.

Getting 10 grenades may also be a problem, as grenades fallen from enemies that have been stuck tend to explode.

This medal is particularly difficult to get as splash damage from exploding grenades may kill you and end your spree.
